The standard valves have the major disadvantage that they can break on engines with a significant increase in power or with long mileage. The standard valves are hollow inside and sodium-cooled. With the very thin valve stem of only 6 mm, there is not much material left to protect the valve! Supertech valves offer the following advantages: High temperature resistance Strong tear resistance Special heat-treated material High strength material Black nitrided Supertech valves are made from an extremely heat resistant alloy. The Supertech valves are suitable for engines with turbocharging and nitrous oxide injection where high exhaust temperatures are used. Available in original size and 1mm oversize. For 1mm oversize valves, the valve seat must be adapted. The kit contains 12 valves without valve keys. Suitable Supertech wedges are required. These can be found below at accesories.
